SPINNING MACHINE.

Application filed July 8, 1926, Serial No. 121,138,. and in Germany May 21, 1926.

This invention relates to a spinning maing rollers 22'are' arranged in front of the chine in which the fibres are sucked, by a funnel mouth 13. funnel, into a hollow conical body which has The operation is as follows spiral-shaped grooves and which terminates As the pulleys 6 are loosely mounted on .in a point leading to the mouth of the funthe shafts 2, which consists of screw spin- 60 nel. The hollow conical body is rotated by dles, they are pressed by the centrifugal aca friction wheel gear consisting of a cone tion onto the cone 7 so that the shaft 8 and mounted on the axle of'the hollow conical with it the conical hollow body 9 are rapidbody and of driving disks mounted on two 1y rotated. "By the exhauster16 on one of driving shafts in the shape of'screw spindles theshafts '2 the air is sucked off from the 65 and exerting a positive action upon the cone funnel 10 and the air current flowing by the centrifugal power transmitted to through the intake funnel into the vacthem. uuin produced sucks the fibres, in which An embodiment'of the invention'is shown, come from the stretching rollers 21,- and 15 by way of example, in the accompanying blows the same against 'thehollow conical 70 drawing in 'which body 9.

The length of thespinnihg cone is selected according to requirement and if the funnel ,is adjustable in axial direction the space between spinning cone and funnel w ll can be madenarrower If the spinning operation is started a thin wire is inserted into the fibres whereupon the thread is pulled by hand out of the mouth ofithe funnel and inserted between The compressed air or the impregnated steam is preferably supplied to all the spindles from a central station. preferably impregnated bya solution of 0, 1 to 1% of a very eftective'mucilage whic dilutes "in the steam and has a favorable action upon the textile fibres.
